Ross, La Fayette, Ind, assignor to Itostone, Incorporated, La Fayette, Ind., a Corporation of Indiana Application August 15, 1932. Serial No. 623,947

4 Claims.

This invention relates to window sash operating devices, and while designed for use in connection with the window sash and frame shown in my co-pending application filed July 18, 1932, Serial No. 623,266 (Case #7958) is applicable to other types of window construction, and the like, wherein slidable sashes, or the like, are employed.

The invention provides simple geared sash operating devices whereby any sash may be raised or lowered at will by the operator and held in any adjusted position.

The accompanying drawings illustrate the present preferred embodiment of the invention and some modifications thereof, and I will describe the same with reference thereto, and summarize inthe claims the novel feature of con-. struction and novel combinations of parts for which protection is desired.

In said drawings:

Fig. 1 is a transverse sectional view through a window frame and sashes, such as described in the aforesaid application, equipped with my novel sash operating devices, the sash being broken to show thesash operating parts more clearly,

Fig. 2 is a side view of the sash operating devices shown in the right side of Fig. 1.

Fig. 3 is a view sim'lar to Fig. 1 showing modifications of the sash raising devices.

Fig. 4 is a detail section on line 4-4, Fig. 1.

In Fig.1 four sashes S, S, S and S areshown slidably mounted in the window frame F which sashes and frame are shown as constructed in my aforesaid application. One of the side bars .of each sash is provided with a rack indicated at s, s, s and s in Fig. 1. The racks extend the length of the sash and are engaged by operating gears as hereinafter described. As shown in Figs. 1 and 4 the rack s of sash S meshes with a gear lb on a tubular shaft 1 which is rotatably mounted in bracket 2 which may be formed on or attached to the outer side of the frame F, the shaft 1 being rotatable and also slidable in the bearing 2.

The outer end of the tubular shaft 1 may be provided with any suitable means for engagement with an actuating wrench or key (not shown) and as shown in Fig. l a socket member 10 is attached to the outer end of the tubular shaft 1 and is adapted to be engaged by any suitable tool by which it can be pushed inward and also turned. On the opposed faces of the bracket 2 and the gear lb are interengaging lugs and slots. Preferably the lugs 2c are on the bracket 2 and the slots 1e are in the face of the gear lb.

A spring 3 is arranged exterior to the tube between the socket member 10 and the bracket 2 with a gear lbr on a to move the shaft 1 outwardly so as to hold the lugs and slots in engagement as shown in Fig. 1 and when so engaged it is impossible to turn the shaft 1 and gear 1b. It is evident that if a crank or key is properly inserted in the cap member 10 and pushed inwardly the shaft 1 will be moved inwardly and move the gear 1b out of engagement with the lugs 2a while maintaining its engagement with the rack s and then the shaft 1 may be turned so as to rotate the gear 1b and raise or 5 lower the sash S by reason of engagement of the gear teeth therewith.

After the sash has been adjusted to the desired position the inward pressure on the operating member is released and the latter withdrawn and spring 3 moves the'assenibly (shaft 1 and gear 119) outward interengaging the lugs and the slots 2a and 1e and firmly locking the sash S in adjusted position.

To operate the sash S'i a'shaft i is extended axially through the shaft 1 and may have an inner bearing in the bracket 2e attached to the frame F as shown. On'this shaft 4 is mounted a gear 4b which meshes with the rack s on sash S and this gear 41) has radial slots 4e which so are adapted to mesh with radial lugs 2, on an adjacent bracket 29 on frame F. A spring 3a is interposed between the gear 4?) and bracket 2e and normally tends to push the shaft 4 and gear 4?) outwardly and hold slots is in engagement with the lugs 2f. 7

The shaft 4 may be squared at the end and preferably projects beyond the member, 10 sufficiently to enable a suitable lever or key, to be applied thereto and when so applied the shaft 4 and gear 4b can be pushed inward so as to disengage the slots 4e and lugs 21 and when so disen gaged the shaft 4 and gear ib can be turned so as to raise or lower the sash S.

Where a window has but two sashes to raise and lower, the devices described would be sufficient to operate same. In some cases, as described in the aforesaid application, four sashes are used and the operating devices are substantially duplicated at the opposite side of the frame 1 0 F. In this case the rack s on the sash S meshes tubular shaft 1a. which is journaled in the brackets 2:0 and 22 attached to the frame F. Gear lbw has slots lea: engaging lugs 2am on the bracket 2.2. The shaft 19: is provided on its outer end with a socket 1am and is moved outwardly by a spring 3:0, the parts described being operated sim'lar to the shaft 1 and members connected therewith above described.

The rack s on sash S meshes with a gear 4hr having slots 4cm engaging lugs 2m on the bracket member 29x, the shaft 4a: and gear 4121? being pushed outwardly by a spring 3am interposed between the gear 4bx and part 2er shown.

The shaft 42: and gear 4hr operate to raise or lower the sash S in the manner above described for shaft 4 and gear 4b.

In the construction shown in Fig. 3 three sashes S, S and S are shown. In this case the rack s on sash S is engaged by gear ID on tubular shaft 1 which may be extended outwardly and have its outer end internally hexed as indicated at 1p for engagement of a suitable operating tool, the sleeve being journaled in a bracket 2 attached to the frame F. A spring 3 is interposed between the bracket 2 and a Washer or collar 11' fast to the shaft 1 as shown. The aforesaid parts are operated as Fig. 1 to raise and lower sash S.

The rack on the sash S is engaged with the gear 4b on the shaft 4 which extends into the shaftl and through a bracket 27' on the frame F. In this instance the shaft 4 is provided with an internal square orhexed socket as indicated at 4h for engagement of a suitable operating tool. The shaft 4 and gear 41) are normally pushed outward by a springSa interposed between a collar 4lc fixed on the end of the shaft 4 and a member 270 attached to the frame F. The parts are operable to raise or lower the sashes S, Fig. 3, in the manner above described for similar parts in Fig. 1.'

The third sash 8 shown in Fig. 3, may be a glazed sash but is shown as a screen sash; the rack s thereon meshes with a gear 4ez on the shaft 42 similar to shaft 4, the shaft being journaled in brackets 262 and 2 10 attached to the frame F at opposite shaft 4; is normallyforced outward by a spring 3&2 interposed between the bracket 210 and the collar 410 on shaft 42. The outer end of shaft 42 has a socket 4h for engagement with-an operative tool.

In the construction shown in Fig. 3, instead of a positive clutch engagement between the gears and brackets, friction clutches may be employed. As shown, a friction disk 5 is interposed between bracket 2 and the gear 1b. A friction disk 5a is interposed betweenbracket f and the collar/4k; and a friction disk 52) is interposed between bracket 2w and the gear 4e2. When the gear 1?) is moved inwardly it will disengage clutch 5 but will be reengaged therewith'as soon as the inward pressure on shaft 4 is released. Similarly when gear 4b is pushed inward the collar 4k will be disengaged from the clutch 5a but will be reengaged therewith when the shaft 4 is moved outward; and when gear 46.2 is moved inward it will be disengaged from clutch 51) but will be reengaged therewith as soon as the pressure is released.

It isevident from the drawings and description that if a suitable crank or tool is engaged with the outer end of any one of the inward the gear connected with such shaft will also be moved inwardand disengaged from the clutch or device which normally prevents its ro tation, and the sash can then be raised or lowered by turning the shaft. As soon as the endwise pressure on the shaft is released the spring will force the shaft and gear outwardly and the a plurality of independently above described in connection with sides of the gear 4ez. The

shafts and pushed 42m: on the shaft 4a: similar to shaft 4, the gear clutch will reengage and lock the gear to the frame and hold the sash in adjusted position.

The outer ends of the shafts can be arranged for either an exterior or interior means for nonrotarial engagement with the crank and when the crank is engaged and the shaft pushed in then the related sash can be raised or lowered at will.
